Ecosystem Threat Status and Protection level was calculated as part of the National Biodiversity Assessment process for 2018. These two metrics indicate the current status and protection level of South Africa’s ecosystems as determined by the National Biodiversity Assessment 2018 Process. The data forms the foundation for many land use decision

The status and protection levels calculated for the NBA 2018 are based on the 2018 National Vegetation Map and the 2009 and 2014 land cover datasets. The IUCN ecosystem assessment method was applied. Previous National Biodiversity Assessments (i.e. 2011 and 2004) produced results for threat status and protection level. However, these were not based on the IUCN system. Therefore the results from previous ETS and EPL layers are not comparable over time.
